Truthfully, removing “Shut down all servers” is not desirable. In the event there is a serious data issue, lets say the latest update has a problem, how can we force a migration as fast as possible? “Shut down all servers” does exactly that.
You also have to account for soft updating systems, systems that use the InsertService or Packages to update assets cleanly. The feature proposed here will not update those servers, forever keeping them on old builds. You have not provided any API that we can hook into what so ever.
The solutions provided by Roblox saying to private the game is harmful. Privating the game removes all private server subscriptions.
This is a reckless change with no forethought given.
